When you go out for a night of fun with your friends to the local bar, you should be able to know when not to drive. Unfortunately, alcohol can quickly turn an evening into a DUI arrest or worse. The problem occurs when you or a friend feel overly confident that driving is OK based on feelings alone.

Protect yourself and the community when you purchase an Alcomate digital breathalyzer from Think Twice. We provide our customers with the best breathalyzers and education to help people understand when they have had too much to drink, and determine with accuracy, when people are unfit to drive.

How Our Products Differ

At Think Twice, we understand that a drunk driving incident can not only destroy a person’s driving record and career, but it can also place innocent people at risk. Alcohol can be fun, but it should always be used responsibly. A personal digital breathalyzer is a simple tool to determine when you should not drive. If you have indulged in a drink or two, think twice before you decide to get behind the wheel. A quick breathalyzer test can save lives and ensure your safety. Our tools are simple to use, easy to maintain, and provide you with fast and accurate results.

The Alcomate breathalyzer is a small device that does not require calibration to maintain accuracy. After you have used an Alcomate for a year to determine your breath-alcohol-content, you simply replace the PRISM sensor like a battery, and you are ready to test again with guaranteed accuracy. All other digital breathalyzer products require the customer to mail their device to the manufacturer to be manually calibrated. Eventually, the sensor in those devices become so corroded they can’t be calibrated and turn into a paper weight that ends up in the garbage.

Think Twice breathalyzers can help set the precedent that you care about yourself and the lives of others. Additionally, you can determine exactly when you should opt for a ride home instead of driving yourself. We believe that proper education and breathalyzers can be used to prevent DUIs and make communities safer.

The AlcoMate Premium digital breathalyzer with Prism Technology was developed to improve the way breathalyzers are maintained for function and accuracy. Once the sensor becomes degraded resulting in a loss of accuracy, you can literally remove and discard the existing module containing the sensor and replace it with a newly manufactured, pre-calibrated sensor module in its place. Replacement is quick and easy, and replacing the module is the only way to restore true “day one” accuracy to your device.

With the exception of the AlcoMate Premium, every fuel-cell breathalyzer in the world must be periodically re-calibrated by the manufacturer in order to maintain maximum accurate readings. It is inherent to alcohol sensing technology, much like gasoline engines in cars require oil changes in order to function properly. Most breathalyzers have to be physically mailed to a service center along with a fee to get this re-calibration done. This video shows the calibration process in a clean environment.

Sensor modules must be replaced every 200 tests or at least once yearly, whichever comes first. Modules should also be replaced if damaged or expired.

Wait 15 – 20 minutes after consuming alcohol before using any type of breathalyzer. It is recommended to drink water prior to taking the test as a way to remove alcohol or any other products in the mouth.
